What is the role of the cathode in anaphoresis?

In anaphoresis, the cathode serves as the active electrode, which plays a crucial role in the process of ionization and the movement of ions. Anaphoresis is a method in electrotherapy that utilizes a direct current to drive negatively charged ions into the skin. When current is applied, the cathode, being negatively charged, actively draws in positive ions from the surrounding environment, such as the skin and tissues. This action promotes the penetration of substances into the skin, enhancing absorption and treatment effectiveness.

The significance of the cathode as the active electrode lies in its ability to facilitate this movement of ions, thereby allowing for various therapeutic benefits, including hydration, soothing irritation, and delivering active ingredients more effectively during treatments.
